IMPROVEMENT IN SKYLIGHTS.

Sf;ecfication forming Part of Letters Patent No. 171,856, dated J anuary4,1876; application filcd October :28, 1875.

Improvement in Skvlights, 0f rvhich the following is a specificacion:

Our ixnprovement is designed as an improvement npon tl1e Letters Patent166,890, granted to us August 17, 1875, and is intended t0 en able us tomanufacture the bar in such a manner as to materially cheapen itsconstruction withont materially lessening its value in use.

Onr invention consists, tirst, in snob a formation of the bar With itsdouble gntters and cap as a whole as that the lower gntter is of thesame form snbstantially as the cap, both being donbled back in a novelway over the inclosed wcbs of the bar proper, and one serving toconnect, by rivcting, the sheets of the bar-ai: the bottom together,while the other stifiens the sheets of the bar et the top.

Our invention fnrther consists, in connection with the bar" l1avingseparaced sheets at the bottom, of a lower gntter, which, by itspecnliar formation and the addition of rivets, forms, by the use of asingle sheet et metal,

water-wayson both sides of the bar, and firmly connects the sheets ofthe bar together at this point.

Figdre 1 is asectional view et ont improved bar. Fig. 2 is a perspectiveview of the same.

A is the snpporting bar, bent together or.

doublent the top to form the crown-web a, and then bent away under theglass at an acnte angle t0 web a, to form a gntter, and also asnpporting-\veb, a for the plate of glass B. The metal isthen bronghttogether at the bottom to form adouble thickness, chus leaving out inthis sheet the secondary gntter for draining themoistnre from the nndersideof the glass, mentioned in our former patent. The bar thus farcompleted has a closed crown-web, a, ofdouble thickness, and anintervening gntter and snpporting-web, a, for carrying off influx ofwater, soot, &c., and snpporting the glass B. The only differencebetween the crownplicated, after bending over and back, at d Tliis cap,when applied to the base of the bar,

is so secnred that the double elongation con,

nected.at d embraces the two parts of the base-web a while the concaveportions extend ontward and npward to form gnttcrs for dtai1iing tl1emoistnre from tire nnder side. of the glass, in place of those mentionedinformer patent. As seen in the drawing, the cap D, thns constrncted, issecnred to the web a by means of rivets, and serves t0 greatly stiffentire bar, while being of cheap constrnctien. The cap Eis a cap similarin formation to cap D, and issecnred t0 crown-web a as said cap Dissecnred t0 base-wcb The lips e l'est npon the gl-ss, and ..arepreferably inclined from a perpemlicnlar; but they may be similar to thelips d on cap D. T0 keep out soot, cinders, &c., 1 provide a line ofpntty, F, nnder cap E.

We clain1 1. A bar for sk'ylights, having on its upper side a donbledcap, E, riveted to the web a, and a lower gutter of the same form,donbled to connect by rivets with the separate sheets of the bar at thelower side, snbstantially as set fortin.

2. In combinaiion with the bar A, the donbled single sheet D, formingboth sides et the lower gnttcr, and serving, by riveting, to connecttl1e separate sheets of the bar togexher, snbstantially as set fortin.

In testimony of which invention we hareunto set onr bauds.
